PySofia is a python wrapper around the methods present in the C++ sofia-ml library. These include Stochastic Gradient Descent implementations of some ranking algorithms, notably RankSVM.

Dependencies

• cython >= 0.17
• numpy
• sklearn >= 0.15
• six
• enum34 (for Python versions before 3.4)
• A C++ compiler (gcc will do)

You will not need to install sofia-ml since it is incuded in this distribution

Installation

::

$ pip install pysofia

Methods

pysofia.train_svm

Trains a model using stochastic gradient descent. See docstring for
more details.

pysofia.compat.RankSVM implements an estimator following the conventions used in scikit-learn.
